Hello bloo.tomartoI think you need to do both of the things you've suggested.

Let the distance between his house and the station be km. Then, using the formula:

- the time he takes to cycle one way is hours.

- the time he takes to ride one way is hours.

- the time he takes to motor one way is hours.

Finally, the time to ride + time to motor = 2 x time to cycle one way hour. So we get:Can you complete it now? (Hint: Begin by multiplying both sides by to get rid of fractions.)

(I make the distance between his house and the station km.)
